Tank: 16l Clearseal Lighting: TMC Mini LED 400 Filter: Fluval Edge HOB Heater: None CO2: JBL ProFlora u500 Hardscape: Dragon Stone Plants: Micranthemum micranthemoides, Hemianthus callitrichoides 'Cuba' and Fissidens fontanus. I put this tank together last year with items I had boxed away. Thanks to @jarcher1390 for both the tank, and filter! I'm still to source a permanent CO2 system for it however (SodaStream), whilst justnow I will use a JBL ProFlora u500 canister and diffuse in-tank via an atomiser. I had some Micranthemum stems growing in a windowsill, alongside a jar of Fissidens. I bought a tub of In-vitro HC, and planned to carpet the tank with that. I didn't have any way of heating the tank, and living in an old farmhouse in Scotland-I knew that growth would be slow. I've since moved the tank next to a radiator which keeps the glass warm at least. With spraying every 2/3 days, it has taken a few slow, winter months to get to this stage. Flooding should be soon though, so I thought I'd kick off a journal! I will flood the tank with soft rainwater, mixed 50/50 with slightly harder natural spring water (straight out the tap!) CO2 will be on permanently for the settling in process, with lights at 100% (no controller for the MiniLED). I'll start EI ferts around 2 weeks in, providing the plants don't show demands sooner! Fingers crossed for a smooth transition, I've been watching this tank evolve for weeks and weeks now and can't wait to flood it! Root structure on all the plants is substantial, and the moss has been growing with vibrant green curls. Any tips before I go ahead with it? Does anyone foresee a problem having no heater? Thanks for looking!
